  • Cover plate for a crank case
    Patent number: 7066133
    Abstract: A cover plate is provided for closing a crankcase of an internal-combustion engine on its underside. The cover plate has a suction point for collecting lubricant from the crankcase. With respect to the crankcase, the suction point is closed off by a screen plate. This screen plate comprises a first area with passage openings for the lubricant and a second area which is impervious to the lubricant. The screen plate has the effect that a reliable lubricant intake from the suction point is ensured even in the event of a tilt of the internal-combustion engine.
